it was suposed to be 85-90 last time i checked before this morrnigns change to now 95-100 so if your even 4 days out dont count on it being cool as it now gives a week out cool temps like i saw a week ago for my trip and now its gona be HOT so just be ready for it to be hot even if it says its cool now
Looking on the brighter side, it may make any pool time that much more enjoyable.
I am sure it will be great regardless. Invest in a mister/fan. I paid about $20 for the one in the parks, but you can find cheaper at Target, etc.
